Abstract

A method for machining a bearing ring of a rolling bearing includes clamping a blank for the bearing ring in a machining machine, and applying a pulsating pressure using a machining body to structure and simultaneously harden an annularly closed sealing surface of the blank. The machining body may be a spherical machining body. The method may also include removing material from the blank to produce a bearing ring track using the same clamping. The blank may be rotated during the applying a pulsating pressure step and the removing material step.

Claims

exact text as granted — not AI-modified
1 .- 10 . (canceled) 
     
     
         11 . A method for machining a bearing ring of a rolling bearing, comprising:
 clamping a blank for the bearing ring in a machining machine; and   applying a pulsating pressure using a machining body to structure and simultaneously harden an annularly closed sealing surface of the blank.   
     
     
         12 . The method of  claim 11 , wherein the machining body is a spherical machining body. 
     
     
         13 . The method of  claim 11 , further comprising removing material from the blank to produce a bearing ring track using the same clamping, wherein the blank is rotated during the applying a pulsating pressure step and the removing material step. 
     
     
         14 . The method of  claim 11 , further comprising displacing the bearing ring blank in an axial direction during the applying a pulsating pressure step. 
     
     
         15 . The method of  claim 14 , wherein the machining body applies the pulsating pressure to the annularly closed sealing surface in a helical line. 
     
     
         16 . The method of  claim 14 , wherein the machining body applies the pulsating pressure to the annularly closed sealing surface in a wavy line that intersects itself multiple times. 
     
     
         17 . The method of  claim 11 , further comprising displacing the bearing ring blank in a radial direction during the applying a pulsating pressure step. 
     
     
         18 . The method of  claim 17 , wherein the machining body applies the pulsating pressure to the annularly closed sealing surface in a spiral line. 
     
     
         19 . The method of  claim 17 , wherein the machining body applies the pulsating pressure to the annularly closed sealing surface in a wavy line that intersects itself multiple times. 
     
     
         20 . A method for producing a rolling bearing comprising:
 providing the bearing ring of  claim 11  with the annularly closed sealing surface comprising depressions;   providing a second bearing ring;   placing a plurality of rolling element between the bearing ring and the second bearing ring; and   installing a seal onto the second bearing ring such that is contacts the annularly closed sealing surface.   
     
     
         21 . A rolling bearing, comprising:
 a first bearing ring comprising a hardened surface having a plurality of depressions;   a second bearing ring;   a plurality of rolling elements arranged between the first bearing ring and the second bearing ring; and   a seal fixed to the second bearing ring and contacting the hardened surface.   
     
     
         22 . The rolling bearing of  claim 21  wherein the rolling bearing is a wheel bearing.
